Ultraviolet light climate Test Chamber ageing resistance test of mobile phone barrel coating

The UV aging Test Chamber plays an important role in the application of mobile phone lens barrel coating. Mobile phone lens barrel coating refers to the coating of a special film on the surface of the mobile phone camera barrel to improve optical performance, enhance wear resistance and scratch resistance. In the daily use of mobile phones, the camera barrel is exposed to various environments, including ultraviolet radiation, humidity, high temperature and chemicals. In order to evaluate the durability and stability of the coating, the UV aging Test Chamber can simulate these environmental conditions, accelerate the aging process of the coating, and conduct performance evaluation.

Test method

The following are the specific steps of the UV aging Test Chamber in the application of mobile phone lens barrel coating:

  1. Material selection and preparation: Select the coating materials for mobile phone barrels that meet the requirements. Commonly used coating materials include silicon nitride (SiNx) films, zirconia (ZrO2) films, etc.

  2. Set test conditions: According to the test requirements, determine the UV radiation source, temperature, humidity and radiation time parameters in the Test Chamber. These conditions should be able to simulate the real UV radiation and mobile phone use environment.

  3. Installation sample: Fix the mobile phone barrel sample on the sample table of the Test Chamber to ensure that the coated surface is exposed to UV light source. It is necessary to ensure the surface integrity and consistency of the sample.

  4. Start the test: Start the UV aging Test Chamber and expose the sample to simulated UV radiation. According to the set test conditions, the radiation is for a certain period of time. At the same time, the damp-heat cycle can be selectively performed to simulate the real use environment.

  5. Monitoring and recording: Regularly monitor and record the performance changes of mobile phone lens barrel samples. Appropriate instruments and equipment, such as surface roughness meters, film thickness Testers, etc., can be used to measure and record the optical properties, wear resistance and surface quality of the coating.

  6. Evaluation results: According to the test data and evaluation indicators, analyze the aging degree and performance changes of the coating samples. Compare the differences between different test samples to evaluate the durability and stability of the coating.

Industry standard

In the UV aging test of mobile phone lens barrel coating, you can refer to the following industry standards:

  1. ASTM D4587: "Standard Practice for Fluorescent UV-Condensation Exposures of Paint and Related Coatings"

    • ASTM D4587 is a standard issued by the American Society for Testing and Materials (ASTM) for the aging exposure testing of coatings and related coatings in a UV-condensing environment. This standard can be applied to UV aging testing of mobile phone barrel coating materials.

  2. ISO 4892-2: "Plastics — Methods of exposure to laboratory light sources — Part 2: Xenon-arc lamps"

    • ISO 4892-2 is a standard published by the international standards organization (ISO) concerning the exposure of plastic materials to laboratory light sources, including xenon lamps. Although this standard mainly applies to plastics, some of these test methods can also be applied to UV aging testing of mobile phone barrel coating materials.
